Lower eyelid skin is the thinnest skin over the body. Any hollowing in this area wrinkles the skin and makes the veins prominent.
Dark skin individuals sometimes develop dark circles under the eyes very prematurely.
This is the commonest area that benefits the most from fat grafting. The lost volume between the eyelid and tear trough is filled with tiny fat cells layered above each other to smoothen it out. After a few months the skin becomes firm and the veins disappear.
Sweling and bruising is common after Liposculpture. Multiple passes of the thin blunt cannula causes good amount of bruising and the downtime is around 2-3 weeks. Eventually it fades away, but you need to be patient before that happens.
